com plete ver ifi ed solu tions +
r ationales (PASS
GUARANTEED)
Sensory Imput (functions) - Neurons pick up information
Integration (functions) - Decision process
Motor Output (functions) - Is the response
What makes up the Central Nervous System? - Brain & Spinal Cord
Parts of a Neuron: - Dentrite, Cell body, Axon, Axon Hillock, Sunaptic
End Bulb
Dentrite(s) - Sensory imput, part that recieves information
Cell Body - Contains the Nissl Substance (black substance within
neuron)
, Axon - The part that sends Action Potential
Axon Hillock - Is the part that starts at the beginning of the axon and is
where the action potential starts
Synaptic End Bulbs - Is the large end of the axon and contains the
neurotranmitter vesicles
When a threshold has been reached so has a_____________. - Action
Potention
Myelin Sheath - Is the lipid installation around the neuron and it also
speeds up the action potential
White Mater - Is myelinated and has the myelin sheath
Gray Mater - Is non-myelinated and lacks myelin sheath
Groupings of Neurons - Nerve, Ganglia, Tract, Nucleus
Nerve - Is a group of neuron processes in the perpherial nervous system
